Product Family:
Part Number Series:
Ultra Precision SMT Resistor Networks
SR Series
Construction:
High Purity Alumina Substrate
Ni alloy thin-film resistive element
Wrap around electrodes
Available in RoHS and non-RoHS
versions. RoHS version is 100% matte
tin over Nickel.
Features:
Various Sizes
2 to 8 resistors/package
Resistance tolerances to 0.02%
Tracking tolerances to 0.02%
TCR as low as ±5 ppm/°C
TCR tracking of ±1, ±2 or ±5ppm/°C
Description:
These surface mount resistor networks feature wrap around electrodes in various product sizes. The number of
resistors in the package is either 2, 4 or 8. Because all of the resistors are fabricated together, these networks offer
extremely tight tracking and TCR tracking tolerances that are difficult to achieve by using individual discrete resistors.
